Application filed August 31, 1914;. Serial No.1859,4r47.

To all whom it may concern.'

Be it known that we, CHARLES C; `SULa LrvAN and Louis PnNNGToN DAVIS, citizens of the United `States, and residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Stump Removers and Destroyers, of which the following is a speciiication.

rl`his invention relates to certain new and useful improvements in stump removers, and relates particularly to a machine for the removal and destruction of stumps, roots or other debris, particularly adapted for use on what are known as cut off lands, the invention having for its primary object the destruction of stumps, roots, etc., in such form that they may be readily handled and utilized for commercial purposes, or piled in such way as .to be destroyed by burning.

Another object of the invention is to provide a machine or device of the character stated, so constructed that it may be manipulated so as to work upon the stump, root, or other object in a manner best calculated to eectually split the same so that it can be removed from the earth.

A still Jfurther object of our invention is to provide in a machine of this character, means whereby the .same motive power as is used for the operation of the machine as a stump destroyer, may be employed for operating a block and tackle mechanism.

Various other objects are sought to be accomplished by our invention, which will appear hereinafter as the invention is more particularly `*described and then claimed, and in describing the invention in detail, reference will be had to the accompanying drawings showing a practical embodiment of the invention as it has been practised by us, without however, intending to limit ourselves to theprecise construction herein shown, since in the practice of the invention, various changes and modiica'tions may be made in the Ydetails without departing Jfrom thel spirit of the invention as herein shown, described andcla-imed.

In the drawings: Figure 1 is a view in side elevation of a stump destroyer in accordance with vour invention. Fig. 2 is a vview of the 4same in front elevation. Fig. -3 is kan enlarged horizontal sectional view taken on the line III- III of Fig. 1. Fig.

Y power around over t is a transverse vertical sectional View taken on vthe line VV--IV of Fig. 1 on a somewhat enlarged scale. Fig. ,5 is a horizontal sectional vieuT on a somewhat enlarged :scale taken on .the line VV of Fig. 1, and, Fig. 6 is a detail perspective View of a ,portion .of the .ax member.

A machine in accordance with vour invention in practice, is mounted upon a suitable truck :that is moved by any desired motive .the land being operated upon. vAs such .truck forms no part of the present invention, it is not illustrated in detail, 'the `element 10 in Fig. l representing the truck diagrammaticaliy.

The devicelembodies a Vframe consistingo'f a pair .of vertical or upright side bars and a pair ,of horizontal side bars, the vertical or upright bars being `design-ated as 11, and in practice, we have usually made the same of channel irons. These are secured to each other at `desired points between their AeX- tremities by brace kbars 12 usually of angle irons .as shown.

The horizontal side bars .or beams vare designatedby the refereneenumeral 14 and these .beams are bored near their outer .ends for the reception of a shatt 15 which also extends through `the npriglrts 11, the latter being :bored for .the reception of said shaft near (their lower ends, the shatt 15 having a loose tit both the beams 14 and the uprights l1. The bea-ms 14E are supported at their rear .ends upon the extremities of a shatt 116., thesuppont tor which will be hereinafter referred to.

`On the front ofthe uprights 11 are .crossbraces 17 which `torno a support for a cylinder 1S that is Ysuitably secured thereto and provided with valve chests v19, 120, at its upper and lower ends respectively. The inlet 27 for fthe stern, :air or other motive ltluid leads .into :the chests 19 r and 20. The valves are centrolled by a suitable valve rigging indicated :in general at 29..

The cylinder has its 4piston rod 4:2 projecting through the lower cylinderhead 4:8, the latterbeing v.usually feonstrgucted in practice with fa stuiftng `box 44: @as shown. rilhe piston rod extends downwardly 'and V*is stead-ied by meansfot fa casting 45 which is attachedto lthe Tlorwand ends of y:the beams 14 and `tothe side aces et :the `uprights A11, Vthis casting being'provided with a suitable bearing tor the piston 'nodoso fthat ithe lat- .Y 65,. when loosened .in

terwill be` Lguided and steadied in vits. strokes.

Detachably lsecured to the lower end ofV the piston rod is the aX member 46, that is usually made in the form of a steel casting,

which may be screwed or pinned on to the piston rod. This member is provided with a ldetachable 'cast'steel cutting edge @t7 which is countersunk inthe aXinember so that its outer face will be flush with the the aX member, there* .by protecting theVV .cutting Ablade against reakageand interfering in no way with the cutting andV splitting` action of they ax member.y rlllhe aX member is provided with holes 48, and 49, respectively, extending entirely therethrough from opposite sides near'the upper end of the member. These holes are for-two purposes, vfirst to permit of. a readyturning of the aX by inserting a bar sc that the aX and piston rod and piston may be'turned around to position the ax as` may be desired. i The second purpose for which these holes are provided fis to permit the utilization of the device -in conand tackle, one end of the tackle as will be later described, being' connected to aclevisO carried vby a pin 51 which, is inserted into either hole L18 or hole 49. Y

The upper end of the upright frame carries ay beam 51 "from which is suspended a sheaveblock orvpulley.V 52, the rope element and tackle passing around to clevis 50, rand carrying the other sheave block 54 with which connection lis made to thestump as 55. .l

@n the truckl() is mounted a support consisting of a base plate 56 which is firmly bolted or otherwise secured to the supportwhich receives a casting 58, through which Y constitute bearings for Y sleeved onto the end operat1ng lever 66 having a spring-pressed extends and has keyed to its upper end a worm wheelU 59. The casting 58 has two forwardly-projecting. brackets 60 constitut ing bearings vfor the shaft 16, and inwhich the said shaft-'isnormally secured against rotation by set screws 61. Rising from the bearings 60V are short standards 62 which .a shaft 63 having a worm 65ste mesh with the worm wheel 59. @n this shaft 63 isa `ratchet wheel 65 and of the shaft is an pawl'67 to engage the ratchet wheel 65, the

pavvl being manipulated'soas to engage with and disengage itV from the ratchet Wheel by the finger lever 68 carried vby the e 60 lever66. l

LLoosely fitted onto the shaft 16 inside .of the beams 14 arel angle braces'69, the upper endsiof which arefastened by `bolts, 70 to the uprights 11, these bolts having a play slots 71 in said uprights llower end of the Rising therefrom isa yshaft 57 11. The bolts are held in position and prevented froin dropping out when loosened by guard plates 72 attached to the-outer faces of the uprights 11.

Such being the detailed construction of the device embodying our invention, the operation of the same is as follows:-With the piston head 2O at the lower end of the cylinder as shown in Fig. 2, the operator grasps lever 31 at the free end and depresses the same, causing'v it to rotate on pivot pin and through the connection at 30 with the rod 29, rests said rod and through the couplings 28 connecting the rod to the stems of valves 21 and operates said valves, so as to open inlet port 25 at the cylinder to admit motive iiuid beneath the piston 26, causing the latter to rest in the cylinder 18. rlfhis positioning of the valves brings exhaust port 23 into communication with exhaust pipe As thepiston moves upwardly in the cylinder 18 and strikes trip rod 36, it operates rod 29 through the connections 38, 35, so as to reverse the valves, opening inlet port 22 and exhaust port 26. rlhc motive fluid being now above the piston 2G, the latter will be driven down, so as to drive thc aX member into the stump or other object being operated upon. The blow which will be struck will of course depend entirely on the pressure of the motive fluid employed, and on the size of the apparatus as constructed. i

Adjustment of the frame to raise or lower the same as may be desired according to the being' manipulated so as to utilize the ax and cylinder as a jack to raise or lower beams 14 as they rotate on shaft 16. soon as the beams 14 have been brought to the desired position, set screws 61 are tightened. This has of course moved the frame embodying uprights l1 and the parts carried thereby out of the vertical position, which isnot desirable, since it has been found that the grain of most trees approximates a vertcal position whether the tree be located on level ground or on a hillside. .Therefore, to bring the uprights 11 and the parts carried thereby again into the vertical position, the ai: member is lowered on to the stump or other object being operated upon, the bolts 70 are loosened so that they will play in the slots 71, member 60 rotating around sha-ft 16. Now, either by working the piston up and down or by moving the tractor 10 backward or forwardas desired, the u1- rights 1l will be revolved around shaft 15,

and as soon as they have been brought into the desired vertical position, they are held by the tightening of the nuts on bolts 70. It will be obvious by this constructionthat the uprights may be positioned obliquely so as to strike ablovv upon a long tap root or the like to split the same, which could not be done by a blov.T directly from above the same.

By manipulating the lever 66, it Will be obvious that the shaft 63, its Worm 64; and Worm Wheel 59 Will swing the mechanism in the arc of a circle so as to correctly position the same over the object being operated upon.

In practice, the device described is generally mounted upon a traction engine Which will also furnish the motive power for operating the engine of the device described, but obviously, it may be mounted on any suitable vehicle, and the motive fluid for operating the same may be obtained from any desired or convenient source.

Wie desire to call attention to the fact that by the use of the device, We are able to split stumps or the like so that they may be readily removed, and yet be in such condition that the same may be used for commercial purposes as in the making of Wooden blocks for pavements, shingles or the like. I.Ve also desire to call attention to the fact that the aX is vmade With a straight and an inclined side, giving the function of a Wedge, yet obviating the sticking action which would take place in case the ax were of a purely Wedge form, that is inclined on both its opposite faces.

By the use of the block and tackle, or derrick attachment, We are enabled to utilize the same machine for dragging the stumps out of the Way and placing them in convenient piles for burning or for use other- Wise as may be desired.

While We have entered into details of the construction as the invention has been practised by us, We desire it to be understood that We do not limit ourselves to the construction shoWn and described, but claim such variations thereof as may fall Within the scope of the invention as claimed.

What We claim is l. In a device of the kind described, a main frame, a supplemental frame adapted to carry a tool and projecting from the main frame, said supplemental frame being pivoted at one end to the main frame, uprights on the supplemental frame, said uprights l being pivoted at their lower ends to the supplemental frame, means to adjust the in clination of the uprights to the supplemental frame and a reciprocating tool and means to reciprocate the same carri d by the uprights in substantial parallel relation to said uprights.

2. In a device of the kind described, a main frame, a supplemental frame adapted to carry a tool and projecting from the main frame, said oted at one end to the main frame, uprights on the supplemental frame, said uprights being pivoted at their lower ends to the supplemental frame, means to kadjust the inclination of the uprights to the supplemental frame comprising bars pivoted at their inner ends to the supplemental frame, pivot pin guides on the uprights, and pivot pins in said guides and extending through said bars and a reciprocating tool and means to reciprocate the same carried by the uprights in substantial parallel relation tosaid uprights.

In testimony whereof We aiiiX our signatures in presence of tWo Witnesses.
